Jelmar CLR PRO CL4PROEA Calcium, Lime and Rust Remover, 28 oz Bottle

Wonderful product. Especially good for cleaning the barrel on my rifle. Cleans all carbon Just collage it inside the barrel over night!!

Great product, it removed a stain that was so stuck on a toilet we were thinking about buying a new one. Let it sit a while so that it can work its magic.

This rocks and works well on hard water deposits here in Texas!

Very easy to use remove the dirts I definitely keep use it

CLR Blasts, Dissolves, and Zaps exceptionally well for a plant based product and is highly recommended for use in our household.

I recently tried the CLR PRO CL4PROEA Calcium, Lime, and Rust Remover, and I’m thoroughly impressed. This 28 oz bottle quickly tackled some of the toughest mineral build-up on my faucets, showerheads, and even in my dishwasher. It’s incredibly effective—within minutes, hard water stains and rust marks disappeared without much scrubbing. The formula is powerful but doesn’t have an overpowering chemical smell, which is a huge bonus. It works on a variety of surfaces, and I’ve used it on everything from porcelain to stainless steel with no damage or discoloration. Highly recommend for anyone dealing with mineral deposits or rust issues!

I was originally disappointed because I used around 60% CLR and 40% water and let it soak for 24 hours and it pretty much did nothing at all to the calcium. Vinegar seemed to be way more effective and cheaper too. White Distilled Vinegar costs $4 for 128 oz, whereas CLR costs $12 for 28 oz (three times a much for almost 1/5th the amount). That means that CLR costs around 12-15x as much as vinegar.But then I tried the CLR a second time. This time I used 100% CLR and 0% water. It did a great job of removing the calcium, so I was happy.I am probably supposed to use fresh batches of CLR each time, but I used a metal strainer and will try reusing the CLR again in the future. I am supposed to clean my warm mist humidifier every two day and CLR is too expensive to be using fresh batches each time. Cleaning Vinegar is slightly stronger than White Distilled Vinegar and costs around the same, so I will try alternating between Cleaning Vinegar and pre-used CLR to keep my humidifier clean.CLR is good at removing rust too. I put a few drops on a screw that I could not remove from a saucepan handle and it removed around half of the rust.
